  • Patent number: 10500585
    Abstract: The present invention provides methods, systems, assemblies, and articles for extracting restrained liquid (e.g., surface tension-restrained liquid) from open wells in a chip, where the restrained liquid does not flow out of the wells due to gravity when the wells are held upside down. For example, the present invention provides extraction fixtures that may be attached to, and/or held adjacent to, a chip such that any restrained liquid that is forced out of the open wells is collected by, or flows through, the extraction fixtures. Also for example, the present invention provides assemblies composed of a extraction fixture attached to, and/or held adjacent to, a chip, and methods of subjecting such assemblies to a force such that at least a portion of the restrained liquid in the open wells is forced out and collected by, or flows through, the extraction fixture.

The second filter unit is fixedly connected to a water outlet on a bottom of the filter bag and defines a second water filtering space in the filter bag. A filter material is provided in the second water filtering space. The outer bag covers the filter bag, such that a water storing space is formed between the outer bag and the filter bag. The water filtering device is conveniently portable and saves any assembling procedure, and can effectively filter water and store the filtered water.

  • Patent number: 8875904
    Abstract: A circular filtering disc and a filter device having the filtering disc. The filtering disc includes a circular partition plate having an inner hub and an outer rim, with radial inlet holes formed in the outer rim and introducing water to the partition plate, and a vertical outlet hole formed in the center of the inner hub and discharging pure water; and a filter fabric placed on or below the partition plate, wherein water supplied to the filtering disc passes through the filter fabric and becomes concentrated at the vertical outlet hole, and is discharged from the filtering disc through the vertical outlet hole. In the filter device, raw water is supplied through the circumferential edges of the circular filtering discs stacked on top of one another in the filter device and is filtered prior to being discharged from the filter device through the center of the filtering discs.

  • Publication number: 20140319046
    Abstract: A method for forming a nanopore membrane includes forming an array of carbon nanotubes on a substrate that are disposed side by side in a direction perpendicular to a length of the carbon nanotubes. The array of carbon nanotubes are embedded in a patternable polymer material. The patternable polymer material is crosslinked over the array of carbon nanotubes. An adhesive layer is deposited on the polymer material having the array of carbon nanotubes to form a pad. The pad is rolled using a transfer rod to form a membrane with carbon nanotubes of the array, forming nanopores through the membrane such that as the pad is rolled the membrane increases in diameter.

    Abstract: A coalescing filter element provides an integrated filter element with a three stage design with a hydrophobic or hydrophilic coalescing layer. A coalescing filter element comprises: a) At least one particulate filtration layer; b) A coalescing layer promoting coalescing of water particles, wherein the coalescing layer is downstream of the at least one particulate filtration layer relative to the flow of fluid through the element; c) An annular coalescing space downstream of the coalescing layer; d) A sump in a lower portion of the filter element in fluid communication with the annular coalescing space; and e) A hydrophobic layer downstream of the annular coalescing space, wherein fluid being cleaned by the element flows through the hydrophobic layer. The coalescing layer may be a hydrophobic or a hydrophilic coalescing layer. A filter assembly will include the coalescing filter element of the present invention.

  • Publication number: 20140305886
    Abstract: An apparatus for filtering dry film solvent includes a hollow vessel having a side wall, an open top end and a second end that includes a main outlet that allows fluid to flow out of a hollow interior of the vessel. A removable cover closes off the open top end of the vessel. The apparatus also includes at least one fluid inlet port formed along the side wall of the vessel and defining an entrance into the hollow interior of the vessel and at least one fluid outlet port formed along the side wall of the vessel and defining an exit from the hollow interior of the vessel. A removable filter member is disposed within the hollow interior and is defined by a frame and filter media that extends across the frame such fluid flowing into the hollow interior through the main inlet must flow through the filter media to reach the main outlet. The filter media is disposed at an angle other than 90 degrees relative to the frame of the filter member.

  • Patent number: 8858789
    Abstract: A system for cleaning up an oil spill and recovering the spilled oil includes frames supporting superhydrophobic oil-absorbing nanowires. A first container supports the frames with the nanowires. A mixture of oil and water is pumped into the first container where the oil from the mixture is absorbed by the nanowires as water is separated from the mixture and deposited in the first container where it is then pumped therefrom. A second container supports the frames with the oil so-absorbed by the nanowires. The frames with the oil so-absorbed by the nanowires are heated whereby the oil so-absorbed separates from the nanowires and is deposited in the second container. The oil so-deposited in the second container is then pumped therefrom.

    Abstract: A portable water treatment device that utilizes a foot-powered actuator to impel water through a filter is disclosed. The actuator moves to generate negative pressure that draws water to be treated into the interior of a housing, then moves to generate positive pressure to impel the water thus drawn in through a filtration device and to impel treated water out of the device. In some embodiments the water treatment device includes two actuators that are coupled to move in tandem.

  • Publication number: 20140263009
    Abstract: A sustainable Low Water Footprint Re-circulating Aquatic System for cultivating aquatic organisms and plants. The system conserves water and energy by using gravity to move water and nutrients from the clarifier into the low water footprint management system. The novel water management system controls the volume of water in the plant grow bed such that it never rises to or above the surface, limiting evaporative water loss. Water flow to the plant grow bed is intermittent and the water management system retains water within the grow bed by capillary action, even when there is no water input. The grow bed contains microflora that convert nitrogenous wastes produced by the aquatic organisms to nitrogenous compounds useable by the plants. The clarified water is then pumped back into the animal tanks. The system is sustainable, cost effective, and highly productive, and uses 50-80% less water than conventional re-circulating aquatic production system.
